Soft tissue chloroma diagnosed by fine needle aspiration cytology. A case report.

A case of soft tissue chloroma diagnosed by fine needle aspiration cytology is reported. The smears revealed numerous large, granular promyelocytes, rare eosinophils and metamyelocytes. The promyelocytes showed many Auer rods (faggot cells). The histologic sections of the excised tumor confirmed the cytologic diagnosis of chloroma. The patient developed leukemia seven months after excision of the chloroma.
